Cards think David Johnson can be 'one of the best'

David Johnson is a dream for those who play fantasy football -- a big, fast, agile running back and an outstanding receiver who scores a lot of touchdowns.

They expect big things from the 24-year-old second-year pro. So do the Arizona Cardinals. And those expectations are enormous.

"David has all the tools," Cardinals running backs coach Stump Mitchell said, "to be -- given longevity -- one of the best backs ever to play that game."

Fantasy Impact:

The story said six running backs were drafted in 2015 before the Cardinals selected Johnson. And as anyone who has watched the "All or Nothing" video series chronicling last season knows, Johnson was not Arizona's first choice as a running back. A scene shows the Cardinals about to select Nebraska's Ameer Abdullah in the second round when Detroit snatched him away one pick ahead of them. Johnson is a low-end first round selection this year. Chris Johnson and Andre Ellington could also factor in, but injuries have affected both of those backs in recent years.
